The bar is oriented at an angle of 30 degrees to the dotted line as indicated in the figure. A force of magnitude F and pointed to the right is applied to one end of the bar. What is the torque about the axle that is being applied to the bar by the force F? 30° F L Hint: think carefully about angles. O FL O FL OLConsider a block sitting on the ground. In 2 dimensions, the height of the block is 1.65 m, and the width is 0.35 m. There is a force F=47 N applied at the top left corner of the block, and the mass of the block is 27.0 kg, distributed equally throughout the block. What is the torque that the force of gravity generates around the bottom right corner (the location indicated with a red x on the image). Give your answer in units of Nm, to three significant figures. You can treat the block as 2 dimensional. The image is not drawn to scale.Rank the pictured torques on a solid beam from most negative to most positive. The black dot in the beam is a fixed pivot axis which is located at the very end of the beam (notice that c, e, and f have different pivots!). You may assume that forces are either applied at the end or the center of the beam. Angles that appear to be 90 degrees, are 90 degrees. If torques are equal in magnitude, please indicate this. If any of the torques are zero, please indicate this.

- To study torque experimentally, you apply a force to a beam. One end of the beam is attached to a pivot that allows the beam to rotate freely. The pivot is taken as the origin or your coordinate system. You apply a force of F = Fx i + Fy j + Fz k at a point r = rx i + ry j + rz k on the beam. 1. Enter a vector expression for the resulting torque, in terms of the unit vectors i, j, k and the components of F and r. 2. Calculate the magnitude of the torque, in newton meters, when the components of the position and force vectors have the values rx = 3.03 m, ry = 0.035 m, rz = 0.085 m, Fx = 2.8 N, Fy = 4.8 N, Fz = 5.8 N. 3.

Imagine a meter stick set up as in the figure. It hangs from a central bracket, and two hanging masses can hang from it from each of their brackets. At a third location, a force probe can either pull up or pull down on the stick, depending on what is needed to balance the stick. The mass of the meter stick is 120 g. sketch the situation (drawing r1, r2, r3, F1, F2, and F3) and determine the magnitude (value) and direction (+ or -) of each torque. Don't include the mass of a bracket that would hold the hanging mass in place; assume the mass listed is the entire mass hanging at that point.
